Add special characters to Asp.net RegularExpressionValidator for E-Mail

Question

I have a e-mail address validator but I need to add special characters as valid for example ü, ç... Because users in Turkey (or anywhere else) can have a web site url like: hasangürsoy.com My code is below:

<asp:TextBox ID="tEMail" runat="server" />
<asp:RequiredFieldValidator ID="rfvEMail" runat="server"
    ControlToValidate="tEMail" ErrorMessage="* required" />
<asp:RegularExpressionValidator ID="revEMail" runat="server"
    ControlToValidate="tEMail" ErrorMessage="* invalid"
    ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" />

Okay I've rewriten the expression like this: \w+[\wçığöşü]+([-+.']\w+)*@\w+[\wçığöşü]+([-.]\w+)*\.\w+([-.]\w+)* the only problem is the e-mail address and domain should start with normal character (not çığöşü). If I solve this problem the work will be done — HasanG, Mar 31 '10 at 06:28

You can use the special format "\u00fc" to specify the hex value of the char. Look at the table here http://www.ascii.cl/htmlcodes.htm

Could you please explain how to use this in the expression? – HasanG Mar 29 '10 at 14:00
Like any other backslash operator like \. (dot character) [\.\u00fc\u00e7]+ – Jacee Apr 19 '10 at 14:51

Okay I did it. But be careful, if you use this e-mail validation expression the mail address can't pass validation when you try to use it for example ReplyTo address.

<asp:RegularExpressionValidator ID="revEMail" runat="server"
    ControlToValidate="tEMail" ErrorMessage="* invalid" Display="Dynamic"
    ValidationExpression="\w*[\wçığöşü]+([-+.']\w+)*@\w*[\wçığöşü]+([-.]\w+)
    *\.\w+([-.]\w+)*" />
